  • Patent number: 8980172
    Abstract: An odor control system includes a controlling gas source, a gas sensor module for detecting a dominant gas, the gas sensor module, a sample conduit, and an electronic control unit. The controlling gas source supplies a controlling gas to react with a foul air gas in a foul air volume. The gas sensor module for detects a dominant gas and generates a detection signal. The sample conduit routes reacted gas from the four air gas volume to the gas sensor module. The electronic control unit is configured to receive the detection signal from the gas sensor module and to automatically control the controlling gas source in response thereto. The detection signal has a signal direction relative to a signal baseline set such that the signal direction will differ depending on whether the controlling gas or the foul air gas is the dominant gas.

  • Patent number: 5667558
    Abstract: A scrubber apparatus and controller includes an outlet gas sensor, and a processor operatively connected to the outlet gas sensor and a treatment chemical supply pump for controlling a level of treatment chemical in scrubbing solution responsive to the sensed undesired constituent, such as hydrogen sulfide and/or other odorous gases associated with wastewater. Accordingly, the controller enhances reduction of the undesired constituent in the gas being treated and while conserving consumption of treatment chemical. To enhance the operating life of the outlet and inlet gas sensors, the processor preferably only periodically exposes the gas sensors to gas, and also periodically supplies purging air to the gas sensors. The controller preferably includes an environmentally resistant housing containing the processor means and the outlet gas sensor. In addition, the inlet gas sensor is also preferably included to provide feed forward control and also to provide a log of both inlet and outlet gas readings.
